Abstract
An electric conduction heating device having an electrically conductive container (20), an upper electrode (16) and a lower electrode (12), wherein material accommodated in the container (20) can be heated by supplying electric current to the container (20) while the upper portion and bottom portion of the container (20) are sandwiched by the upper electrode (16) and the lower electrode (12); the container (20) being provided with a lower barrel (20a) and an upper barrel (20b) whose electrical resistivity is lower than that of the lower barrel (20a). This electric conduction heating device can efficiently heat the material accommodated therein.
